Subject [jira] Updated: (HADOOP-5188) Modifications to enable multiple types of logging
Date Thu, 14 May 2009 20:35:45 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-5188?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Luca Telloli updated HADOOP-5188:
---------------------------------

    Attachment: HADOOP-5188.patch

the attached patch supports: 
- parsing dfs.name.edits.dir arguments as URI 
- introducing a new abstraction named LoggingDevice. The subclass named FileLoggingDevice
should incorporate StorageDirectory (work in progress). The idea is that FileLoggingDevice
should be treated as the current StorageDirectory (when the directory is of type EDITS or
IMAGE_AND_EDITS) while other types of logging should be treated according to their respective
properties. 
Two methods (namely getInputDeviceClassName and getOutputDeviceClassName) should get the class
name of the EditLogInput/OutputStreams associated with this type of device. 

the patch passes successfully namenode unit tests
